Originally created by @anarcat on GitHub (Jan 7, 2012).

I see that ~ was removed as a separator, but i think it has its uses. It's actually what Debian uses to mark release candidates as being "lower" than the real release. In fact, it makes the whole thing semantically easier to compare.

Consider: a.b.c > a.b, as a general case. If we say that "dot" can separate "release candidates" strings, then this is not true if c is "rc1", for example (1.0.rc1 < 1.0), breaking the general case (for that matter, 1.0.rc1 > 1.0.0).

So I think that ~ serves a purpose and should be brought back in, which would also mean that this would be compatible with the Debian versionning.

For more information about Debian version numbers and the way they are compared, see: http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version

"~" was replaced with "-", not ".". That can be compared programmatically.

I see, then it's not so bad! :) I still think it's unfortunate to needlessly diverge from an existing policy (Debian's), it would have been very useful for porters as they could have used the semver versions directly.

In Debian dash ("-") is more like semver's plus sign ("+"), which is also allowed.

I don't like Debian's versioning paradigm. It's overly complex. If you re-read the spec, I think you'll see that it covers how to compare versions very explicitly and with a small number of easy to understand rules.

In addition, Git tags cannot contain the tilde character, making it badly suited to modern development.
